Abstract
The invention relates to a cable protection method and particularly relates a process for machining a tin-plated screening layer of a cable. The process provided by the invention uses a dropping manner in processes of adding and coating a soldering flux, so that the soldering flux is uniformly coated on the surfaces of a felt by dropping the soldering flux into the felt and passing braided wires through the felt. An adding amount of the soldering flux is controlled by controlling a dropping speed. Furthermore, a turbulence pump driven by a motor is additionally arranged in tin plating equipment, so that an oxidation film is difficult to generate on a tin surface due to flowing. With the adoption of the process, the problem of influencing electric properties of the cable, caused by that the traditional process cannot entirely dry and remove water and oil impurities in the braided wires to be capable of ensuring the firmness of tin immersion, can be solved. Meanwhile, the problem that a cable screening layer is easy to generate needle holes or dark spots, and the problem of influencing the quality of the tin-plated surface, caused by that the tin surface very easily forms a film through oxidation in a tin immersion process to cause non-complete contact of tin and the braided wires, can be solved. Therefore, the electric properties and the surface quality of a product can be improved, and the product scrap rate is reduced.
Description
Technical field

This kind of processing cable shield generally all is directly to immerse cable in the scaling powder at present, scaling powder will be immersed in the screen like this, and in road, back baking operation, just be difficult to thoroughly oven dry, remove moisture and grease impurity in the litzendraht wire, therefore can not guarantee the fastness of wicking, so that influence the electric property of cable, and cause cable shield pin hole or stain to occur easily.The tin face is easy to oxidation filming in the wicking process, causes tin to contact with litzendraht wire not exclusively, influences zinc-plated surface quality.
Summary of the invention
For electric property and the surface quality that improves product, the present invention researches and develops the zinc-plated screen processing technology of a kind of cable.This technology adopts the dropping liquid mode in the process of interpolation and coating scaling powder, scaling powder is splashed in the felt, and litzendraht wire passes in felt, and scaling powder is coated on the litzendraht wire surface uniformly, by the speed of control dropping liquid, control the addition of scaling powder simultaneously.In addition, in tin equipment, add motor-driven turbulence pump, the tin surface current is moved, be difficult for forming oxide-film.
The technical scheme that the present invention is taked for achieving the above object is: the zinc-plated screen processing technology of a kind of cable, it is characterized in that: finish interpolation and coating scaling powder, skin drying, wicking and draw whole technical process by the production line that is made of pay off rack, dropper, drying unit, tin equipment, pulling equipment and take-up stand, its concrete steps are as follows:
(1), interpolation and coating scaling powder
At first several pieces felts being put into scaling powder soaks, several pieces felts that will soak then are fixed on the felt seat of dropper, by adjusting the dropping liquid control valve in the dropper, scaling powder in the dropper vessel is constantly oozed to felt layers, with the scaling powder humidity that keeps being soaked with on the felt layers, when litzendraht wire passed the felt layers that is soaked with scaling powder, the scaling powder on the felt layers was coated in the surface of litzendraht wire equably;
(2), skin drying
Add and apply and carry out skin drying by drying unit after scaling powder is finished, bake out temperature is set in 130 ℃～150 ℃;
(3), wicking
With the tin liquor in tin equipment heating, heating-up temperature is 280 ℃～300 ℃, and the litzendraht wire of skin drying is immersed in the tin liquor of fusing;
(4), traction
Is 5 meters/minute by pulling equipment with the speed setting of production line, to control the thickness of zinc-plated surperficial tin layer.
Described dropper comprises the scaling powder vessel, have the dropper of syringe needle, be fixed on dropping liquid control valve on the dropper, fixed head, bolt, felt layers, and felt seat, wherein, the dropper upper end that has syringe needle is connected with the scaling powder vessel, felt layers is built up by several pieces felts, syringe needle on the dropper is pricked on the felt layers upper surface, litzendraht wire is by passing in the felt layers, two fixed heads place the bottom and the upper surface of felt layers respectively, and by bolt two fixed heads and felt layers are fixed on the felt seat.
The beneficial effect that the present invention produced is: adopt this technology to solve traditional handicraft because of can not thoroughly drying, remove moisture and the grease impurity in the litzendraht wire, and then can not guarantee the fastness of wicking, so that influence the electric property problem of cable, simultaneously also avoided cable shield to occur the problem of pin hole or stain easily, the tin face is easy to oxidation filming in the wicking process, cause tin to contact with litzendraht wire not exclusively, influence zinc-plated surface quality problems.Thereby improved the electric property and the surface quality of product, reduced the product rejection amount.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.As shown in Figure 1, the present invention finishes interpolation by the production line that is made of pay off rack, dropper, drying unit, tin equipment, pulling equipment and take-up stand and applies scaling powder, skin drying, wicking and draw whole technical process, and its concrete steps are as follows:
(1), interpolation and coating scaling powder
In order to make tin can be coated in the surface of litzendraht wire equably, litzendraht wire carries out the interpolation and the coating of scaling powder before zinc-plated after pay off rack puts down.At first several pieces felts being put into scaling powder soaked 1 minute, several pieces felts that will soak then are fixed on the felt seat of dropper, syringe needle on the liquid pipe in the dropper is pricked on felt layers, by adjusting the dropping liquid control valve in the dropper, scaling powder in the dropper vessel is constantly oozed to felt layers, with the scaling powder humidity that keeps being soaked with on the felt layers, the dropper of dropper can adopt the common transfusion pipe, and (the dropper diameter is 4mm, needle aperture is about 0.2mm, scaling powder oozes speed control at 2～3 droplets/second), when litzendraht wire passed the felt layers that is soaked with scaling powder, the scaling powder on the felt layers was coated in the surface of litzendraht wire equably; Ceaselessly inject scaling powder for felt layers by dropper simultaneously, litzendraht wire is coated by felt fully, as brush one deck scaling powder on litzendraht wire, has guaranteed that scaling powder applies evenly, and not many again, is beneficial to follow-up oven dry and handles.
(2), skin drying
Add and smear scaling powder and finish after carry out skin drying by drying unit, bake out temperature is set in 130 ℃～150 ℃ (generally being set in 140 ℃); With moisture in the litzendraht wire and grease Impurity removal, guaranteed the fastness of wicking.
